virtual vtkTypeBool vtkXMLUtilities::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

static vtkXMLUtilities* vtkXMLUtilities::SafeDownCast ( vtkObjectBase o)
static
virtual vtkObjectBase* vtkXMLUtilities::NewInstanceInternal ( ) const
protectedvirtual
vtkXMLUtilities* vtkXMLUtilities::NewInstance ( ) const
static void vtkXMLUtilities::EncodeString ( const char *  input,
int  input_encoding,
ostream &  output,
int  output_encoding,
int  special_entities = 0 
)
static

Encode a string from one format to another (see VTK_ENCODING_...

constants). If special_entites is true, convert some characters to their corresponding character entities.

static void vtkXMLUtilities::CollateAttributes ( vtkXMLDataElement ,
ostream &  ,
const char *  sep = nullptr 
)
static

Collate a vtkXMLDataElement's attributes to a stream as a series of name="value" pairs (the separator between each pair can be specified, if not, it defaults to a space).

Note that the resulting character-encoding will be UTF-8 (we assume that this function is used to create XML files/streams).

static void vtkXMLUtilities::FlattenElement ( vtkXMLDataElement ,
ostream &  ,
vtkIndent indent = nullptr,
int  indent_attributes = 1 
)
static

Flatten a vtkXMLDataElement to a stream, i.e.

output a textual stream corresponding to that XML element, its attributes and its nested elements. If 'indent' is not nullptr, it is used to indent the whole tree. If 'indent' is not nullptr and 'indent_attributes' is true, attributes will be indented as well. Note that the resulting character-encoding will be UTF-8 (we assume that this function is used to create XML files/streams).

static int vtkXMLUtilities::WriteElementToFile ( vtkXMLDataElement ,
const char *  filename,
vtkIndent indent = nullptr 
)
static

Write a vtkXMLDataElement to a file (in a flattened textual form) Note that the resulting character-encoding will be UTF-8.

Return 1 on success, 0 otherwise.

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromStream ( istream &  ,
int  encoding = VTK_ENCODING_NONE 
)
static

Read a vtkXMLDataElement from a stream, string or file.

The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, nullptr otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly.

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromString ( const char *  str,
int  encoding = VTK_ENCODING_NONE 
)
static

Read a vtkXMLDataElement from a stream, string or file.

The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, nullptr otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly.

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromFile ( const char *  filename,
int  encoding = VTK_ENCODING_NONE 
)
static

Read a vtkXMLDataElement from a stream, string or file.

The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, nullptr otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly.

static void vtkXMLUtilities::ReadElementFromAttributeArray ( vtkXMLDataElement element,
const char **  atts,
int  encoding 
)
static

Sets attributes of an element from an array of encoded attributes.

The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding.

static int vtkXMLUtilities::FindSimilarElements ( vtkXMLDataElement elem,
vtkXMLDataElement tree,
vtkXMLDataElement ***  results 
)
static

Find all elements in 'tree' that are similar to 'elem' (using the vtkXMLDataElement::IsEqualTo() predicate).

Return the number of elements found and store those elements in 'results' (automatically allocated). Warning: the results do not include 'elem' if it was found in the tree ; do not forget to deallocate 'results' if something was found.

static void vtkXMLUtilities::FactorElements ( vtkXMLDataElement tree)
static

Factor and unfactor a tree.

This operation looks for duplicate elements in the tree, and replace them with references to a pool of elements. Unfactoring a non-factored element is harmless.

static void vtkXMLUtilities::UnFactorElements ( vtkXMLDataElement tree)
static

Factor and unfactor a tree.

This operation looks for duplicate elements in the tree, and replace them with references to a pool of elements. Unfactoring a non-factored element is harmless.
